The onboard PHM system, leveraging technologies such as 5G and BeiDou communication, intelligent sensors, and multi-network integration, couples to capture the operational status and fault information of all systems. By integrating historical data and environmental factors, it facilitates system status monitoring, fault prediction, and health status evaluation. This enables the self-sensing and self-diagnosis of critical locomotive systems or components, centered around the PHM model. The modular structure is adaptable to various application scenarios, including temporary test data collection and analysis, individual component PHM analysis, and vehicle PHM analysis, while ensuring quick and easy deployment.
Leveraging technologies such as big data, AI algorithms, and data governance, the system utilizes onboard intelligent perception as the frontier terminal. Combined with the ground maintenance resources and the intelligent operation and maintenance platform as the decision-making center, it provides precise maintenance decisions for critical components, thereby enhancing the overall vehicle efficiency while reducing maintenance costs. CRRC Datong Co., Ltd. has established a comprehensive intelligent operation and maintenance system involving users, the company, and suppliers, achieving highly efficient operation and maintenance with the goal of zero-distance service and zero-time-difference response.
